Those ports are used by the underlying pjproject DNS resolver.  The
resolver is always listening on those ports for DNS query responses.  1 for
IPV4 and 1 for IPV6.  Your firewall should only be allowing responses to
flow through to those ports that match outgoing requests.

[asterisk-users] Asterisk 14.0.2 opens a high numbered UDP port

2016-10-13 Thread Brandon B. 
What part of Asterisk 14.0.2 opens the random, high numbered (33094 
currently) UDP port? This port is opened even without any channel 
drivers loaded.


$ sudo netstat -ltunp | grep asterisk
udp0  0 0.0.0.0:51488 
0.0.0.0:*   13830/asterisk
udp0  0 0.0.0.0:5060 0.0.0.0:*   
13830/asterisk
udp0  0 :::42516 :::*
13830/asterisk
